ELECTRIC PARKING BRAKE FORCED RELEASE PROCEDURE

id041200523800

Caution

•  The electric parking brake forced release procedure is performed so that the vehicle can be temporarily moved if a malfunction occurred in the electric parking brake system and the electric parking brake cannot be released by operating the electric parking brake switch. After completing the procedure, move the vehicle immediately to a place where it can be repaired and perform the inspection and repairs.

•  When carrying out the procedure, park the vehicle on level ground, verify the surrounding conditions, and pay attention to safety.

Note

•  The clearance between the disc plate and disc pads is expanded after an electric parking brake forced release, therefore operation of the electric parking brake motor gear unit when the electric parking brake switch is initially operated after the servicing may take longer than normal.

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the wheel and tire. (See WHEEL AND TIRE REMOVAL/INSTALLATION.)

3.  Disconnect the electric parking brake motor gear unit connector.
